Bfp after Mc...

I just got a Bfp on hpt. I told mom, she's excited. I told my aunt, she said I hate to say it but don't get your hopes up since it's only one day of your missed period. The test showed positive right away and is so much darker than last time. I'm having mixed emotions now. My husband is very excited. Said he thinks since it's darker its a good sign. I just don't want to get my hopes up and something happen. I don't know how to feel or who to tell incase anything does happen. Does it matter if the positive is light or dark? I thought if there was two lines no matter what it's positive. She also keeps talking about how she wants her kids to start families. I don't know if that is her reasoning for being so negative to me. She was last time as the line was very faint. Said she didn't think I was pregnant and I went on to have a miscarriage. As that is what my doctor said when I seen him. Sorry for the long post. But if I am one day past missed period and got a strong positive is that a good sign?
